Answer:
   x = 29
Step-by-step explanation:
If the equation is :
4.2(9-x)+36=102-2.5(2x+2)
→distribute 4.2 and -2.5 in parenthesis 
4.2(9 - x) + 36 = 102 -2.5(2x + 2)
37.8 - 4.2x +36 = 102 -5x -5
→  have terms with x = terms without x 
Keep the terms you need the way they are, and move the terms you need on the other side of equal sign with changed sign. 
4.2(9 - x) + 36 = 102 -2.5(2x + 2)
37.8 - 4.2x +36 = 102 -5x -5
  - 4.2x  +5 x  = - 37.8 - 36 + 102 - 5
→ Combine like terms
              0.8x  = 23.2
→ Divide both sides by 0.8
                      x = 29
                     
 
        
             
        
        
        
So the answer is (2c – 3) (2c – 3) or (2c – 3)^2
